Fox Hunting Transmitter
One of the projects I’m working on right now is a self contained package that will consist of a transmitter, battery, timer board and voice ident board all housed inside a 50cal ammo box.

Voice ID Board
This board was taken from a cheap voice recording pen I bought off Ebay. It can only record for 10-13 seconds or so, but for this application it should be enough. I actually bought 2 of these pens, expecting to destroy one in the process of experimenting. Seeing how the first one survived everything (so far) I’ll use the second board to play a different message during the transmissions.
